Actually, iron, cobalt, and nickel ARE all in the same group of elements. If you look on this attachment, you will see iron, nickel, and cobalt are all medals. I circled it for you.

The group is observed vertically throughout the table
And the period is observed horizontally throughout the table
As we can see in the table (see attached file), iron, cobalt and nickel are located next to each other horizontally so they belong to the same period and not to the same group
